Has Yasmin Alibhai-Brown been unseated by Diane Abbott as the stupidest woman in Britain?

If you haven't seen it yet, the must-watch meltdown of the week was Diane Abbott's performance on This Week. Gosh I would have loved to have been in the green room afterwards. For years Abbott, Michael Portillo and host Andrew Neil have chummed away together in the studio once a week. Now with Abbott running for Labour leader, Andrew Neil has turned the full, brilliant, glare of his scrutiny on his fellow star. The look of shock on Abbott's face – as he fired unfriendly questions at her – was simply wonderful to behold. It has cheered me up even more than the sun finally coming out.

If you haven't seen it yet, do watch it here. Several times.

The first question unsettles her. But the second is absolutely devastating. For years people like Abbott, who have built their careers on the simple chance of their skin pigmentation, have flung around accusations of "racism" while making the most outrageously racist comments themselves. Andrew Neil rightly picks Abbott up for saying that "West Indian mums will go to the wall for their children". A statement that strongly implies that white mothers, for instance, would not. As Neil says, turn the comment around and it would be unthinkable that someone would have got away with saying it.

Rather courageously, Andrew Neil goes on to ask the follow-up question: why, if her statement were true, are cases of delinquency among young men of West Indian origin so very high?

If Diane Abbott had any self-respect she would not be appear on Andrew Neil's sofa again. Mind you, if Diane Abbott had any self-respect she wouldn't be touting herself around as Labour leader at least partly on the basis of skin colour and sex – things that, like the rest of us, she didn't choose to be born with.
